I thought I would go ahead and answer this question prompt since Harris Teeter is starting super double coupons Wed.
How does Super Double coupons work? Which coupons are the best to use?
Harris Teeter will only double 20 coupons per day per household. Only 3 identical coupons can be used in 1 transaction. During the super double events Harris Teeter will double any coupon with $1.98 face value or under. For ex. $1.50 coupon will double to $3. They will double any coupon under $1 every day, so for the super double event you need to focus on the coupons that are $1-$1.50. This can score you tons of free stuff.
